METAL WEATHER-STRIP.

Specification of Letters Patent. Patented July 23, 1912.

Application filed February 24, 1912. Serial No. 679,726.

To all whom it may concern:

Strips, of which the following is a specification.

This invention relates to improvements in weather strips which are particularly designed for use on window casings, and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention, is to provide a weather strip, which may be carried in stock by merchants, and can be readily placed in position on the window casing by unskilled persons so as to effectually exclude air and prevent side motion of the window sashes, whereby it will be adapted to correct ill fitting sashes and prevent them from rattling.

A further object of the invention is to I provide a combined strip of wood or molding and a metallic strip fitted thereon and thereto in about equal lengths,- which lengths may vary to correspond with the varying lengthsof different sized window sashes, to the end, that the combined strip of molding and weather or metallic strip, of the requisite length may be purchased from a merchant, and easily placed in positifin on'a Window by a person of ordinary s 1 Other objects and advantages of the invention will be disclosed in the 'subjoined description and explanation.

In order to enable others skilled in the art to which the invention pertains, to make and use the same I will now proceed to describe it referring to the accompanying drawing in which-- Figure 1, is a plan sectional view of a portion of a window casing and a part of the lower sash thereof showing a weather strip embodying one form of the invention secured in operative position to the window frame. Fig. 2, is an enlarged perspective view of the form of weather strip shown in Fi 1, illustrating the wood or molding strip shortened for the convenience of illustration, and Fig. 3, is a similar view of like parts showing a modification in the construction of the strip.

Like numerals of reference refer to corresponding parts throughout the different views of the drawing.

The reference numeral 5, designates a portion of a window casing which may be of the ordinary or any preferred construction, and as usual is provided on the inner surface of each of its upright sides with a groove 6, produced in any welLknown way, for the reception and vertical operation of each of the side rails 7, of the sash. The weather strip consists of a piece of molding 8, preferably of wood which is provided in its surface adjacent tothe sash rail 7, when the Weather strip is in position on the window frame, with a longitudinally disposed groove 9, and on its surface opposite that adjacent to the window .frame with a similarly disposed groove 10, which grooves are by preference located at right angles to onev another as is clearly shown in Figs. 1 and as to be portable therewith, and if desired,

adjustable thereon. The metal strip consists of a single piece which is bent to form a channeled member 11, having on one of its walls a flange 12, which extends inwardly or toward the other wall of said channeled member. This flange is snugly fitted in the groove 9, of the molding, and the other wall 13, of the member 11, is formed by bending the metal strip back upon itself or doubling the same and is snugly fitted in the groove 10, of the molding. Thus it will be seen that a chamieled member 11, rectangular in cross-section is provided which will embrace the correspondingly shaped portion or part of the molding strip and securely connect the parts together. Extended from the outer layer or fold of the wall 13, of the channeled member 11, alongside said member toward the sash 7, is a Wing 14, of the metal strip which is formed integrally with the outer layer or portion of the wall 13, and extends longitudinally co-extensive therewith but is slightly spaced from the body of the channel 11, as is clearly seen in Figs. 1, and 2, of the drawing, unless forced thereagainst by the proximity, of the sash rail 7, to the adjacent I v surface'of the moldin strip 8, which is se- .cured to the wall of t e frame 5, by means of spikes or nails 15, driven through the same into the said frame. The wing 14:, of the metal part of the strip has extended therefrom alongside the'surface of the mold ing 8, adjacent to the sash rail 7, a flange 16, which has near its free edge a deflected portion 17, which will rest against or'contact with the surface of the 'rabbet or groove 6,

of, the window frame in which the sash rail 7, operates. By this arrangement it. is apparent that, as the metal part of the weather strip, is made of sheet metal'which possesses considerable resiliency, the flange l6, having the deflected portion 17, at its free edge, to rest against one of the walls of the rabbet of the window frame will serve to hold the sasli rail 7, closely against the opposing wall of said rabbet in such a manner as to ex- .clude the passage of air, dust, soot, moisture, and the like, and also, in such a manner as toprevent lateral or sldewise movement strip is made, which forms the other wall 12", of the channeled part, 'or bending the same back upon itself longitudinally as shown in Fig. 3, and providing its layer or portion adjacent to the window frame with a wing 14:, to fit between the surface of the molding strip 8, adjacent to the sash rail 7,

and to project at its free edge between one.

of the walls of said sash rail and the wall of the rabbet 6, of the window frame adjacent thereto. In this modified construction,

the wing 14, is provided with a deflected portion 17, at its free edge, which extends co-extensive therewith, with a deflected art 17", which will rest against the wall 0 the rabbet 6, of the window frame and will pre- 1 vent the admission of air and assist in holding the sash frame in position within its guldeway against lateral movement.

Havin thus fully described my invention what I c aim as new and desire to secure by :Letters Patent is-- 1. Alweather strip consisting of a .piece of molding adapted to be secured to the sur face of'the window frame adjacent to the sash rails and rovided on its surface adjacent togtlie sas rail with a longitudinally extended groove-and in its surface op osite that adjacent to the window frame a ongitudinally extended groove, and a single piece of sheet metal bent to for-ma longitudinall extended channeled portion having jacent to the sash rail, the last named Wall having an extensibn projecting toward the other wall of the channeled portion 'and'located in the groove of the molding adjacent to the sash rail and a wingextended from said extension between the molding and sash rail and into the rabbet of the window frame.

2. A weather strip consisting of a piece of molding adapted to be secured to the surface of a window frame adjacent to the sash rail and provided on its surface adjacent to the sash rail with a longitudinally extended groove and in its surface opposite that adjacent to the window frame a longitudinally extended groove, and a single piece of sheet metal bent to form a longitudinally extended channeled portion having one of its walls located in the groove of the molding opposite the surface thereof adjacent to-the window frame and its other wall located along the surface of the molding adjacent to the sash rail, the last named Wall having an extension projecting toward the other wall of the channeled portion and located in the groove of the molding adjacent to the sash rail and a wing extended from. said extension between the molding and sash rail.

3. A weather strip consistlng ofa piece of molding adapted to be secured to the surface of a window frame adjacent to the sash rail and provided on its surface adjacent to the sash rail with a longitudinally extended oove and in its surface opposite thatadacent to the windowframe a-longitudlnally extended groove, and a single iece of sheet metal bent approximately bac upon itself to form a longitudinally extended channeled portion of two thicknesses of material and having one of its Walls located in the roove of the molding opposite the surface t ereof adjacent to the window frame and its other wall located along the surface of the molding adjacent to the sash rail, the last named wall having an extension projecting toward the other wall of the channeled portion and located in the groove of the molding adjacent to the sash rail, and a wing extended from the outer layer of the last named wall between the molding and the sash rail.

4'. As an improved article of manufacture a weather strip consisting of a piece of molding having a pair of longitudinally extended grooves, said grooves bemg located substantially at rlght angles to one another,

one of said grooves of the molding and its other Wall located along the surface of the molding adjacent to the other groove thereof, the last named Wall having an extension projecting toward the other Wall of the channeled portion and located in the last named groove of the molding, and a Wing extended from said extension alongside the surface of the molding in which the last named groove is formed.
